WHEN DARK OUTSIDE RUN THE ENGINE AND OPEN THE HOOD AND MIST THE ELECTRICAL PARTS OF THE IGNITION WITH WATER . iF YOU SEE ANY FLASHES OF LIGHT THAT IS A WEAK SPOT SHORTING OUT AND NEEDS REPLACING.

Aw lets do that first check the timing and get back to me.
Just wondering if you have checked that timing yet?
very well keep me informed .
Just 30 on those cylinders is the problem, Now you have to determine why those two cylinders have low compression by doing a wet compression test as well. This will tell you if it is the rings or valves that are at fault. will you be doing the compression testing? Perhaps you would like to descuss this over the phone it may be faster and easier, your choice .Or we can continue texting. let me know.
Aw that explains the loss of compression then, Make sure you have the head checked for warp age with a straight edge or have it decked by a machine shop.
